The present disclosure is related to automatic collimator installation systems and methods. An automatic collimator installation method may include obtaining an installation instruction for installing a target collimator into a medical scanner; identifying, from a plurality of collimators stored in a collimator storage device, the target collimator based on the installation instruction; using a cart to transport the target collimator from the collimator storage device to the medical scanner; and automatically installing, using the cart, the target collimator into the medical scanner.

For gamma ray detection, 3D tiling is made possible by modules that include a gamma ray detector with at least some electronics extending away from the detector as a side wall, leaving an air or low attenuation gap behind the gamma ray detector. The modules may be stacked to form arrays of any shape in 3D, including stacking to form a Compton detector with a scatter detector separated from the catcher detector by the low attenuation gap where the electronics form at least one side wall between the detectors. The modules may be stacked so that the detectors from the different modules are in different planes and/or not part of a same surface (e.g., same surface provided with just 1D or 2D tiling).

The present disclosure discloses a medical imaging device including a gantry and a first C-arm having an imaging chain. The gantry includes a first supporting arm connecting the first C-arm, a base, a second C-arm connecting the base, and a second supporting arm connecting the second C-arm. The first C-arm may be moveable along the first supporting arm and the second supporting arm may be movable along the second C-arm.

In some implementations, a device may produce, via an x-ray module, x-rays to be directed towards a body part. The device may detect, via a sensor, the x-rays reflected from the body part. The device may generate, via the sensor, signals based on the x-rays reflected from the body part. The device may generate, via a processor, an x-ray image of the body part based on the first signals. The device may transmit the x-ray image to a server. The device may receive, from the server, a message that indicates a diagnosis associated with the x-ray image. The device may display, via a user interface, the x-ray image and information associated with the diagnosis associated with the x-ray image.

A registration fixture for use with a surgical navigation system for registration of medical images to a three-dimensional tracking space includes a base frame adapted to be mounted over a flat panel detector of an x-ray medical imaging device, and a side frame having optical tracking markers mounted to the base frame. The base frame includes a first set of radiopaque markers embedded therein in a first predetermined pattern and arranged on a plane, and a second set of radiopaque markers embedded therein in a second predetermined pattern also arranged on another plane, which is spaced from the first set of radiopaque markers. The side frame has a plurality of optical tracking markers and is configured to detachably mount to the base frame without piercing a sterilizing drape to be interposed between the base frame and the side frame.

A device for attaching an x-ray image detector holder to a commercial structure such as a pipe so that the modern digital image detector can be used in analysis and inspection. The x-ray image detector holder attach device is constructed to be attached to a structure and can include a flat image detector holder part, the image detector holder part having at least one peripheral slot; a structure contact part constructed to be strapped to a structure to be x-rayed, the structure contact part having a key sized to mate with the peripheral slot, the key having a lock constructed to hold the key in the peripheral slot; the structure contact part can be a means to attach it to the structure to be x-rayed such as a strap or suction cups.

An MR-PET apparatus is provided. The MR-PET apparatus may include a supporting component, a PET detection device, an RF coil, and a signal shielding component. The PET detection device may be supported on the supporting component. The PET detection device may be configured to receive a plurality of photons. The RF coil may be configured to generate or receive a radio frequency (RF) signal. The signal shielding component may be placed between the PET detection device and the RF coil. The signal shielding component may be configured to shield the PET detection device from at least part of the RF signal.

Disclosed is an X-ray generation apparatus for intra-oral X-ray imaging, a guide holder, and an X-ray imaging system comprising the same. The X-ray generation apparatus includes a body and a plurality of X-ray sources disposed in different positions of the body, and configured to irradiate X-rays to a field of view, wherein the body moves along a predetermined trajectory for the field of view.

Realized is a pedal mechanism that does not lock and does not provide an operation feeling unless operated in a determined order. The pedal mechanism has first and second pedals 105 and 106, first and second plates 108 and 109, and a locking bar 115. The radius of the second plate 109 is smaller than that of the first plate 108, and the second plate does not come into contact with the locking bar in a state where a circular-arc region of the first plate supports the locking bar 115. Therefore, the second pedal does not give an operation feeling even when stepped on, and the second plate cannot be locked. In a locked state where the locking bar is located in a cutout region of the first plate, the locking bar contacts the second plate, the second pedal provides an operation feeling, and the second plate can be locked.

A digital radiographic detector having a radiolucent cover and housing at one or more edges of the detector allows radiographic imaging using multiple detector arrangements with overlapping edges that do not obstruct radiographic images captured thereby.
